Obviously, we spend a lot of time talking about signatures here at SIGNiX. When it comes to our business, we try to explain the difference between the mere image of a signature associated with a digital document (which is how a lot of simple e-signatures work) and the sophisticated exchange of public and private cryptographic keys that make our true digital signature more secure, more private, and more legally durable.
The point here, whether we're talking pen-to-paper or PDF, is that a signature is so much more than a mark on a page. It's even more than the complex legal ideas it represents. A signature is an artifact that says something about who we are as people, and what we want in a moment of our lives.
